1 Claim. (01. 33-47) This invention relates to sights for firearms, andparticularly to front sights of the so-called hooded type.

Sights of this type comprise a tubular hood hood I is slottedtransversely from the top, the slot I 5 constituting about one-half thecircumference of the tube. It should be noted that the slot is a simpletransverse out, without longitu- 5 adapted to house the sightingelement, protecting dinal projections, bevels or other additional parts5 the sighting element from accidental displaceor surfaces.

Means have thus been provided for removablylocating the reticule correctly within the hood without the assistanceof any parts other than the hood and reticule themselves.
